Specification of Letters Patent.

Patented Sept. 19, 1916.

Original application filed January 22, 1914, Serial No. 813,755. Divided and. this application filed May 27,

[0 all u; ho'm it may concern:

Be it known that I, AnoLrrr ABRAHAM, a citizen of the United States, residing at Rockford, in the county of \Vinnebago and State of Illinois, have invented certain new and useful Improvements in Vindow Bumpers and Latches, of which the following is a specification.

This invention relates to an improved window bumper and latch and is to cover an improved device of the character described disclosed in my prior application bearing Serial Number 813,7 55, filed January 22nd, 1914:.

One of the objects of the invention forming the subject matter of this divisional application is to provide an improved bumper which can be connected with the lower edge portion of a window and which will serve to prevent the window from slamming shut and breaking the glass and then serving as a latch to prevent the window from being opened from the outside.

Another object of the invention is to provide a device of the character described which will be very strong and durable and not liable to be easily bent out of shape and which will operate very efiiciently and securely hold the window in a locked position.

Another object of the invention is to pro- Vide a device of the character described which can be very easily produced, it being formed from a strip of resilient material bent to assume the desired shape.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of a window provided with the improved bumper. Fig. 2 is a sectional view showing the window in a closed position. Fig. 3 is a perspective view of the bumper.

The window 10 is hingedly mounted in the frame 11 as shown at 12 and has the lower bar of its casing provided with a cutout 13 which registers with a cutout 14 in the frame 11 when the window is closed as shown in Fig. 2. It is of course obvious that the bumper provided could be used upon the transom of a door as well as upon a swinging window but it has been shown in connection with a window as this is the connection in which it will preferably be used.

The bumper shown in Fig. 3 is formed from a strip of resilient metal bent to form a bridge 15 having arms 16 and 17 extending Serial No. 30,812.

therefrom. This bumper straddles the lower portion of the window casing and is secured by means of a fastener 18 which passes throughthe opening19 in the upper portion of the arm 17. It should be noted that the arm 17 is crimped to form a finger-hold constituting a spring element 20 thus giving the bumper more resiliency and that the arm 16 is curved to form a second finger hold 21. Therefore when it is desired to open the window a finger can be passed through the finger hold 21 and the'bumper raised to move the tooth 22 out of the notch or cut out 14:.

In assembling, the cut out 13 will first be formed and the bumper then put in place. The small strip 23 which is to be engaged by the tooth 22 as shown in Fig. 2 will then be driven into the window frame at the proper place and the cutout 14 will then be formed so that the tooth can fit down into the cutout and engage the abutment strip 23. If the window 10 is a cellar window through which coal is to be passed intovth-e cellar, the window may be held in an open position either by the means shown in my prior application or by any other means. As soon as the coal has been forced through the window into the cellar and it is desired to close the window the means for holding the window in an open position can be released or removed, if it is simply a temporary support, and the window will then swing to a closed position. In doing so if it were not for the bumper, the glass might be broken by the jar and it is to prevent this that the bumper has been provided. As the window closes the tooth will first strike the frame thus stopping the motion of the window but not to a sufiicient extent to prevent it from entirely closing. As soon as the window has moved to the closed position as shown in Fig. 2 the tooth will move into the cutout and by engaging the abutment strip 23 will prevent the window from being opened unless the latch is raised from the inside by means of the finger hold 21.

I have therefore provided a bumper which will eifectively check the closing of a window but at the same time permit the window to entirely close and releasably hold the window in the closed position. It will also be noted that this device is very simple in construction but at the same time is very effective and also that this device can be very cheaply produced since it is formed from a strip of resilient metal stamped to assume the proper shape.

What is claimed is The combination of a Window frame having one bar provided With a socket, a WindoW sash hingedly connected with said frame, and a U-shaped bumper formed from resilient material, said bumper straddling the freeend portion of said Window sash and having its bridge provided With a tooth for checking the movement of the Window sash toward the closed position and for engaging the socket of said frame to releasably hold the sash in a closed position, the arms of said bumper extending along the side faces of said sash and one of said arms being unsecured and bent to provide a finger-hold.

In testimony whereof I affix my signature in presence of two Witnesses.
